FLANGING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 26,186, dated June 27, 1882.

Application led April 5, 1882. (No model.)

To all whom it may conceww' Be it known that I, SAMSON FOX, a citizen of England, residing at Leeds, in the county of York, England, have invented certain new and useful Improvements in Flanging-Machines; and I do hereby declare the following to be a full, clear, and exact'description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.`

' In the improved arrangement of machinery for Hanging the front or end plates of steamboilers I use a type of steam-hammer having the supporting-columns a anda (or uprights) a good distance apart. 'On the top of them are cast-iron caps b and l, formed to receive a strong wroughtiron double girder, c, on which the steam-cylinder dis bolted.

The pistonrod passes through the gland fY and guide g on the inside of the strong Wroughtiron girder c.

On one sideof the piston his placed another piston-rod or guide-rod, i, working through a gland, j, in the top cylinder cover, 7c. This piston-rod 'i secures a good guide for the main piston-rod c below, and relieves it of requiring any guide other than that of the upper rod j `ust described, and this gives a very free access to the attendants for manipulating their work between the columns and the girders on which the cylinder rests.

The foundation of this hammer is very massive, and arranged to take on an anvil, l, for Hanging the outside flanges of boiler-front plates, and also to take on suitable rings or circular dies, m, for forming the Han ges of the holes in boiler-fronts, through which the Hues of such boilers have topass or be fitted into.

In using the machine for Hanging the boilerfront plate the anvil is arranged to receive a short piece, mmade to the radius or curvature the stud o.

of the required plate. Acenter stud, o, is fixed into a slot, p, forming part of the anvil l, at the proper radius distance for the intended plate. The plate is then heated all round the edge in a suitablefurnace and brought onto The hammer-head g is Htted with a suitable tup or tool, 1', for turning down the Hange by acting on the one side on or against the plate, while on the other it is supported by a girder to hold it upto its work, the horn s forming part of the anvil-block. The plate is rotated by the attendants a short distance between the strokes of the hammer.

The operation of Hanging the Hue-holes in boiler-fronts is as follows: In place of the before-mentioned anvil l, a turned ring, m, suitable in size to receive twice the thickness of the plate and the full diameter of the Hue-hole to be formed, is placed under the tup t of the hammer. This tup is formed with a large circular face. On the under side of this tup t is attached a punch, u, (of suitable diameter to form the hole,) by a single bolt, o. This bolt o has a cotter, zr, passing through it on its upper end, so that a blow relieves the cotter zo, and allows the bolt t to drop, and so frees the punch u. In Hanging a Hue-hole-the plate is heated on a suitable furnace all round the edge of the'hole. The plate is then lifted onto the before-mentioned ringm and placed in correct position by means of suitable stops, a' y z. The tup t of the hammer is brought down and the punch u pressed into the plate.' rlhe cotter w is driven'out and allows the before-mentioned bolt o to drop. The tupt is lifted up and a stout wrought-iron ring, a,in halves, is placed on the punch u. While it remains embedded in the partially-Hanged hole of the plate the tup t is once more brought down and drives the punch through the plate by striking the half rings a', which rest on the face of the punch u. This produces a perfect flange, at

once striking through the plate.

The speed of Hanging boiler-fronts by this machine is twenty times that of doing them by hand, and the cost of attendants in wages per day is rather less, so that the cost of the work is less than one-twentieth of whatit was before the introduction of this machinery.
